Where do I find the engine serial number on a 91 S2? Have looked around the block from below and above and see nothing.

TIA

A quick look at mine (out of the car), and I only find what looks like a build date on the side and a four digit number by the oil pan on the passenger side. Maybe I can look further this weekend.

KuHL 951

It's stamped vertically on the edge of the block where it mates to the bellhousing directly behind the OAS tube and just below the block series stamping. It is centered between the two allen cap screws that hold the sensor bracket onto the block. It's hard to see without a mirror, at least on a turbo it is. A shot of brake cleaner and a rag helps.

I turned the block over and it was much easier to see.

are blocks number matched to VINs?

tdz

It doesn't match anything in the VIN. There is no indication of an engine replacement in the car's well documented history.

KuHL 951

Looks like the 951 block ID is in a different spot. I stand corrected. I assumed the S2 would be the same.

oh i just meant that as a general question, not pertaining to your car in particular

kuhl, do you know if blocks were number matched to cars?
